And imagine you just so happened to get there on the day of the famous volcanic eruption. Your situation might seem hopeless! But it's not. With the help of a little hindsight and a lot of science, Cody Cassidy explains how you can get yourself to safety. Cassidy, author of And Then You're Dead and Who Ate the First Oyster, is a master of explaining how things work in a simple, funny, yet scientifically thorough fashion. "I like learning bone-dry engineering principles like 'dynamic similarity' when they answer whether I could outrun a Tyrannosaurus rex," he says. (Yes, he has also written a very thorough treatise on how you might escape from various dinosaurs.) "And the science of a magma's viscosity can be used to determine the proper escape routes from an erupting volcano. The science writing I like doesn't dumb science down, it makes it understandable and entertaining."
